A scoping review of worldwide guidelines for diagnosis and treatment of Helicobacter pylori infection
Abstract
BACKGROUND: This study comprehensively analyzes the diagnostic criteria, eradication indications, treatment, and other information in the latest guidelines published by various countries around the world, so that researchers can have a systematic understanding of Helicobacter pylori and further provide a basis for clinical H. pylori diagnosis and treatment.
METHODS: Nine online databases were searched to find the latest version of guidelines for H. pylori worldwide. Two researchers read the included guidelines independently and extracted the eradication indications, diagnostic criteria, and treatment in the guidelines, conducting a summary of them.
RESULTS: A total of 25 guidelines or consensus were included. Among all diagnostic methods for H. pylori infection, the urea breath test is widely recommended as the first choice. A total of 20 guidelines mentioned indications for H. pylori eradication. Among them, the indications with a higher proportion of recommendations were long-term use of non-steroidal anti-inflammatory drugs (including low-dose aspirin) in 90% of patients with peptic ulcer history or active peptic ulcer disease 80%; gastric mucosa-associated lymphoid tissue (MALT) lymphoma 75%. It is worth mentioning that 40% of the guidelines pointed out that, as long as H. pylori infection is confirmed, it should be eradicated. A total of 24 guidelines mentioned treatment for H. pylori. Among them, bismuth quadruple therapy (a combination of a bismuth, two antibiotics,…
